Barna. It really depends on what you do with your laptop. The higher your drives rpm's are the faster it can perform read and write opperations. This basically translates into better performance with applications which heavily rely on the drive. Most programs reside in your ram. If you use your pc for gaming, email, and normal every day use then you will see little or no benefit. If you run a server with simulataneous uploads, downloads or you are heavy into commercial marketing. FOr example you compile clips and movies which need to be rendered in a program such as adobe premier which stores the most of what is compiled in non volitile memery (hardrive) then the higher rpm, faster read and write speed of the drives are very beneficial. Hope this helps
